Small watercraft

Abstract

A small watercraft includes an input, a second storage, and a controller. The input receives an operation to switch the small watercraft into one of a plurality of control states, and includes a first storage that stores first control information indicating the one of the plurality of control states associated with the operation received by the input. The second storage stores second control information indicating one of the plurality of control states. The controller is able to write to one of the first and second storages. The input is supplied with electric power by supplying the controller with the electric power. When the one of the plurality of control states indicated by the first control information is different from the one of the plurality of control states indicated by the second control information, the controller causes one of the first control information and the second control information stored in the one of the first and second storages to match the other of the first control information and the second control information stored in the other of the first and second storages.

What is claimed is: 
     
       1. A watercraft comprising:
 an input that receives an operation to switch the watercraft into one of a plurality of control states, the input including a first storage that stores first control information that indicates the one of the plurality of control states associated with the operation received by the input; 
 a second storage that stores second control information that indicates one of the plurality of control states; and 
 a controller configured or programmed to write to one of the first and second storages; wherein 
 the input is supplied with electric power that is supplied to the controller; and 
 when the one of the plurality of control states indicated by the first control information is different from the one of the plurality of control states indicated by the second control information, the controller is configured or programmed to cause the one of the first control information and the second control information stored in the one of the first and second storages to match the other of the first control information and the second control information stored in the other of the first and second storages. 
 
     
     
       2. The watercraft according to  claim 1 , further comprising:
 an engine; wherein 
 the first control information indicates one of a locked state and an unlocked state of the engine; and 
 the second control information indicates one of the locked state and the unlocked state of the engine. 
 
     
     
       3. The watercraft according to  claim 2 , wherein the controller includes an ECU that controls the engine and that is connected to the second storage; and
 when the controller starts the engine and the second control information indicates the unlocked state, the controller is configured or programmed to stop the engine and change the second control information stored in the second storage into the first control information when the first control information indicates the locked state. 
 
     
     
       4. The watercraft according to  claim 3 , wherein the controller is configured or programmed to take a longer period of time after activation thereof to obtain the first control information from the input than to start the engine. 
     
     
       5. The watercraft according to  claim 3 , further comprising:
 a battery; and 
 a main relay connected to the battery, the input, and the controller; wherein 
 the controller supplies the electric power to the input from the battery through the main relay. 
 
     
     
       6. The watercraft according to  claim 2 , wherein
 the controller includes an ECU that controls the engine and that is connected to the second storage; and 
 when the controller starts the engine and the second control information indicates the unlocked state, the controller is configured or programmed to keep the second control information stored in the second storage unchanged when the first control information indicates the unlocked state. 
 
     
     
       7. The watercraft according to  claim 2 , wherein
 the controller includes an ECU that controls the engine and that is connected to the second storage; and 
 the controller is configured or programmed to change the second control information stored in the second storage into the first control information when the first control information indicates the unlocked state but the second control information indicates the locked state. 
 
     
     
       8. The watercraft according to  claim 7 , wherein the controller is configured or programmed to change the second control information stored in the second storage into the first control information without starting the engine. 
     
     
       9. The watercraft according to  claim 2 , wherein
 the controller includes an ECU that controls the engine and that is connected to the second storage; and 
 the controller is configured or programmed to keep the second control information stored in the second storage unchanged when the first control information indicates the locked state and the second control information indicates the locked state. 
 
     
     
       10. The watercraft according to  claim 9 , wherein the controller is configured or programmed to keep the second control information stored in the second storage unchanged without starting the engine. 
     
     
       11. The watercraft according to  claim 1 , wherein the input includes a touchscreen display. 
     
     
       12. The watercraft according to  claim 1 , further comprising:
 an engine; wherein 
 the first control information indicates any one of a plurality of operating modes of the engine; and 
 the second control information indicates any one of the plurality of operating modes of the engine.
